Question

phoenixfire · Answer

Move all the terms with x to one side of the equation. And all terms without an x to the other side. What have you got?

anonymous · Answer

2x=3x=50+5???

phoenixfire · Answer

When you move a term from one side to the other side you have to change the sign.
Here's the proper method:
$$a+b=c$$To isolate b we subtract a from both sides of the equation.
$$b+a-a=c-a$$You can see that a-a=0 leaving you with$$b=c-a$$
A simpler way to remember is to change the sign if you move a term to the other side.
$$2x+5=50-4x$$Move the -4x to the left. and the +5 to the right.$$2x+4x=50-5$$
Can you solve from here?

phoenixfire · Answer

Your answer book is wrong. Or you are looking at the wrong answer. 
x=7.5 is correct if you are solving for x.
